Recall  this property of exponents,

When we apply this property our expression becomes,

.

We rearrange to get

.

We now apply another property of exponents to simplify the numerator.

According to this property,

When we apply this property, the expression will now be,

This simplifies to,

We again apply this property of exponents,

.

When we apply this property, the expression will be,

We rewrite this as a positive index to get,

The correct answer is C
